What does an exclamation mark inside a circle on a car mean?

[LeMason]

Red exclamation mark (specifically a circle with an exclamation mark inside), this represents a warning for the braking system, mainly indicating a braking system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark indicating a braking system fault, all other exclamation marks on a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a general performance or component and function fault in the car. Main issues include parking sensor faults, fuel cut-off system intervention or malfunction, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant oil below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a bracket. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault with the car lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or you can check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the problem.
